Need help with my Rooster and Hens!!

We Got our first set of 5 chickens about 5 or 6 months ago, and one turned out to be a rooster...and then our second set, which are the browns ones about a month or so after them. I am not sure what Breed they are. I am looking for a little help!!!

This is our rooster, My hubby named him Diablo! and then my ladies this is one of the ones we got with the rooster :

Diablo is an Easter Egger. I think your black and gold hens are black sex links (but have no idea how diablo got mixed up with them if they were all supposed to be the same breed). Your new girls look to be red sex links (aka gold stars, isa brown, golden comet depending on who sells them). I have no idea on that random white hen in the background.

The little white hen is Nemo, she our little one that my dog got a hold of and only got her wing, However she is just growing slower than the other brown chickens. I am not sure how he got mixed up in the batch I got,. They were straight run chickens non sexed so there is no telling. I picked him because he was gray when he was a chick and so cute!
